During the setup of Bright OpenStack, if “Ceph” was selected as the back end for Cinder, a Ceph pool will be created and configured as a Cinder back end. In this article we explain how additional Ceph pools can be added manually as back ends for Cinder. In this way the administrator could configure different Ceph pools with a different number of replicas and/or different Ceph topology (e.g. stored on faster, SSD based, Ceph OSDs), and associate different OpenStack volume types with them.

For the examples in this article we assume:

Ceph and Bright Openstack are already deployed

There is a pool, test-pool, defined in Ceph, and the user wants to add it as a back end for Cinder. Step 1 of this article has an example on how a Ceph pool can be created from Bright.
